The way I see it is you’re being proactive with your career and finances, and the same goes for your personal life. You have to be proactive and carve out and create the kind of life you will love. To stop rumination change your focus in the moment onto a positive activity - even if it’s just simply cleaning the house. Switching your focus helps redirect your thoughts to a different activity. Pursue the things you enjoy and fill your life up with joy. The joy always burns out lingering pain. You have one life to live - that’s it. And life can change at any time so create a life worth living and one you’re proud to live.
